WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 610,384, date september e, 1898.

Appleman inea December 28,1897. serial No. 663,978. (No moan.)

To a/ZZ whom, t may concern:

Be it known that I, EDWARD T. BURRoWEs, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in Window-Screens; and'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in window-screens, and more particularly to that class known as sliding screens.

In fitting and adjusting screens to windowframes it is frequently found that the latter is not perfectlysquare and more or less irregular, which necessitates planing vor cutting down the edges of the screen-frame to secure the requisite lit.` When' thewindow-frame is not perfectly square, the rigid square frame of the screen will not lie sufficiently close to the jamb or sill at all points to exclude insects. In view of this fact manufacturers usually construct the screens somewhat larger than is necessary, so as to allow for this after planing off for tting. I/Vhen a iinished painted screen is planed off, the Wood is left exposed to the elements and soon deteriorates unless repainted.

The object of the invention is to provide a structure which will avoid the necessity of cutting the frame or marring the paint when it is necessaryV to adjust or lit it to a windowframe and to also avoid the necessity of repainting or finishing the same.

The invention is embodied in the construction and arrangement of parts hereinafter described, and defined in the claims.

In the accompanying drawings, wherein like letters of reference designate corresponding parts in theseveral views, Figure lis an elevation of a window frame and screen,show ing a part of the latter broken away. Fig. 2 is a detail edge view of an applied justifying device. Fig. 3 is a cross-section on the line 3 3 of Fig. 2. Fig. 4 is an elevation of a modied form of justifying device, and Fig. 5 is an edge view of the construction shown in Fig. 4.

In the drawings is shown a sliding screen ent instance consist of substantially triangular blocks having straight outer concave faces d, in which the bead or track E rests. The under face of the shoe or justifier D is inclined, as at d', and rests on an inclined bottom d2 of a recess D', formed in the edge of the screen-frame. The shoe is formed with a recess d3, entering from its outer face and extending to a point near the bottom. The lower wall of this recess d3 is inclined to correspond with the bottom of the shoe, and it has an oblong slot'cl4 cut therethrough of a width less than that of the recess d3. Passing through the slot d4 is a securingor set screw F, the head ofwhich rests Within the recess d3 and against the bottom thereof at the sides of the groove d4.

The screw F is forced into the molding of the frame at an angle so that the under face of the head will rest firmly against the bottom wall of the recess d3. By loosening the screw F the block or shoe can be moved longitudinally up or down the inclined wall of the molding-recess, and when in its adjusted position the screw can be tightened, thereby locking the shoe in place. Therefore if the window-frame should not be square the screen can be quickly justified by adjusting and setting the shoes, edgewise movement being permitted by the abutment-springs, and a close fit be secured without cutting or marring the screen-frame.

In Figs. 4 and 5 I have shown a modification of the inclined form, and it consists," essentially, of a circular shoe G, located in a recess F', formed in the" side of the'molding. This shoe has a concaved peripheryor beadengaging surfaceand is eccentricallymounted on a pin H, secured tothe molding. h is a curved elongated slot formed through the shoe G concentric with the pivotal point thereof. Passing through this slot h is a set IOO screw K, having a suitable washer thereon resting against the surface of the shoe. By turning theshoe on its eccentric pivot it is forced out from the containing-recess more or less, as occasion demands, and when so adjusted it is secured in place by the set-screw. It is obvious that various changes in the constructions shown and described can be made and substituted therefor Without departing from the nature and principle of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a Window-screen, the combination with the screen-frame, of independent j ustifying devices at the edge thereof consisting of outwardly-movable shoes having elongated openings therein and setscrews passing through the openings for locking the shoes in their adjusted positions, substantially as described.

2. In a Window-screen, the combination with its frame, of independent justifying devices at the edge of the frame, consisting of movable shoes having elongated slots therein, and set-screws passing through the slots into the frame for securing and locking the shoes in their adjusted positions, substantially as described.

3. In a Window screen, the combination with the frame, of a justifying device for the screen consisting of a transversely and longitudinallymovable shoe secured to the frame, means for positively locking the shoe in its adjusted position, and abutment-springs on
